It could be that the Bluetooth system in your car doesnt recognise your phone because it is so new. What kind of car is it? Did you pair your old phone to the car?
It is unusual that a phone won't pair with a car at all. Are you 100% certain you are following the procedure? Can you connect your phone to another phone via bluetooth?
It might even be the case that there is an upgrade to the bluetooth software for your car but you would need to contact your garage to discuss this.
